锻造车间桁架机械手与六轴机器人怎么选｜Gantry or Six-Axis Robot for the Forge Shop

摘要：两种自动化搬运路线各有胜场。按产品族宽度、产线布局、地基条件、十年扩展四个维度对比，给出常见的搭配方案。
Abstract: Two automation routes, each strong in its own field. Comparing by part-family width, line layout, foundation conditions and ten-year growth, with common hybrid layouts.

正文： 锻造产线上自动化搬运的二选一：桁架机械手还是六轴机器人。这个问题没有标准答案，但有一个稳定的判断顺序。
Main text: The forge shop’s automation fork: gantry or six-axis. There is no universal answer, but there is a stable order of questions.

一、四个维度对比
1. Four dimensions compared

• 节拍与刚性：桁架占优，重件长行程稳，适合单一产品大批量。
  Cycle and rigidity: gantry wins — stable for heavy parts and long strokes, best for one product at volume.
• 柔性与场地：六轴占优，占地小、换型快，适合多品种混线。
  Flexibility and floor space: six-axis wins — smaller footprint, faster changeover, mixed production.
• 地基与改造量：桁架要龙门立柱基础，老厂房改造成本高。
  Foundations: gantries need column bases — costly retrofits in older shops.
• 维护与人才：桁架结构简单电工就能修，六轴依赖机器人集成商。
  Maintenance: gantries are simple enough for in-house electricians; robots lean on integrators.

二、常见搭配方案
2. Common hybrid layouts

多数锻造车间的终态是混搭：感应加热到压机用桁架，压机到切边、堆垛用六轴。重载主流程给桁架保节拍，柔性末端给机器人吃换型。一上来就全机器人或全桁架的方案，第二年都会回头补另一半。
Most shops end up hybrid: gantry from induction heater to press, six-axis from press to trimming and stacking. Heavy main flow on the gantry protects the cycle; the flexible tail goes to robots. All-robot or all-gantry plans almost always add the other half in year two.
